Schiffe Versenken is a German phrase that translates to Battleship in English, which is a well-known strategy-type guessing game. The game involves two players who attempt to guess the locations of each other's hidden ships on a grid. The version you are referring to, written by an unknown author and published by an unknown publisher, was developed for the Commodore PET, an early personal computer released in the late 1970s.The Commodore PET version of Schiffe Versenken would have been a digital adaptation of the classic pen-and-paper game, allowing players to input their guesses via the keyboard and receive feedback on whether their shots were hits or misses. The game would have utilized the PET's monochrome display to represent the grid and ships, with simple graphics or text characters to indicate the state of play.
